Trying to create Pacman
Pacman is pretty simple to model


Start by adding a sphere: Shift-A>Mesh>Shphere
Hit F6, in the properties window that is provided, change the segments to 24.
Hit Tab to enter edit mode.
Rotate him by 90o on the X axis, RX90
Right Mouse click while holding Alt on The face loops you'd like to delete for his mouth. You may need to select additional faces using the Right Mouse Button.





Use X>Faces to delete


There are a few more steps to add eyes:


Select a face on the one side you'd like his eye(s) to go over


Snap the 3D cursor to it, using Shift-S>3D cursor to selected
Exit edit mode, Tab
Add another sphere.
Use Shift-S>Selected to cursor to position your eye.
Scale it to the correct size using S
Use ShiftC to re-center the cursor
Use ShiftAltC>Origin to 3D curosr to move the origin of your eye to the center
Add a mirror modifier using the modifier panel.


To animate the Pacman, instead of deleting the faces covering his mouth, split them down the middle ShiftV, and then rotate them to alin with the upper lip. You can use this as a shape key. You will then need one with is mouth closed and you're good to go, simply animate between the shapekeys.

If the shape keys don't provide satisfactory results, You can try using somthing like the hook modifer, with an empty for each row of verts.
